The Document Type Definition (DTD) file that defines the structure of the XML file used
for migration is available on your Address Manager appliance or VM. Launch a web browser
and navigate to the protocol://addressmanager-host/dtd/migration.dtd
file, where protocol is http or https, and
addressmanager-host is the IP address or host name for your Address Manager appliance or
VM. Use this address to view and download the DTD file. You can also add this address to
the header of your migration XML file to validate the file before you perform the
migration.
